This is what Vlad sent me some time ago.
It works for my open end encoders.
This is how to wire up your Renco encoders.
Just leave out the Non inverse wires.

The limitation of open ended encoders is that you are limited in the distance of the cable you can run to them.

I note that Rutex also sells adapters that make your open end encoders to differential encoders. They sell them for $19.00
